Romney won the West Virginia primary with 69.63% of the vote.According to the CD result map, he won each district in the 60% range.Such uniform distribution is indeed possible, but are the results really correct?

One of the main motivations for me to create the site was precisely the lack of some organized central government repository for the data. I agree that there should be some official agency in charge of keeping these data and the official documents beyond the certificates of vote and certificates of ascertainment.

Hi,Whereas the other sources you cite are one-time publications that are a snapshot of the official results as published by the state agencies, the Atlas updates data as errors are discovered to provide the most accurate tally. These include the addition of write-in votes not counted by state agencies, amended results by individual counties, and mistakes discovered through tallying precinct/town results.

Some examples for 2012 include:

Warrick County, IN discovered 3,791 uncounted ballots in March of 2014

Wilson County, KS double-counted ballots

Rockland County, NY - Atlas includes amended results

New Jersey - several counties have amended results

Massachusetts - corrected figures in Easton (Bristol County)

Connecticut - corrected figures in Waterbury (New Haven County)

Many write-in votes included that aren't tabulated by state agencies - over 152,000 votes so far

On the 1900 national map, ND is the >60% shade for McKinley. The result for McKinley is listed as 55.25%.

Hi,Actually, in this case, the map is correct and the data is wrong. Took the opportunity to fix the data, added the county data, updated North Dakota county maps since 1898, and updated all maps for the contributed ND results prior to 1908.

Here is another example - Oakland County, MI 2012 President - Sorted by Republican Win ascending and then by %Margin ascending, filtered for only Cities and total vote > 2,000. Mouseover highlights Bloomfield Hills City on the map.
